| Summary: | Jakarta flooding is currently getting more severe and the performance of both the macro and micro drainage system during the flooding period has never been investigated intensively. This paper presents the evaluation on flooding at East Sunter II area, east part of Jakarta, focused on the hydraul ics performance of the existing system and also the planned polder system and the planned long storage. Hydrologic and hydraulic routing has been utilized to analyze the dynamics of local inundation condition in the nearby polder systems. Three rainfall conditions, i.e. the RIO and the rainfall data of February 2007 and January 2013 floods from nearby rainfall stations have been applied and its significant inundation performance was studied. The evaluation criteria if the water surface elevation of the downstream reach of the Old Sunter River. The model result shows that the two flood events are comparable to the I Oyr flood. Introduction of two polder ponds and normalization of the downstream reach of the Old Cakung River appears to solve the inundation problems of the above floods. |
